Effectiveness of Neuromuscular Electrical Stimulation on Lower Limbs of Patients With Hemiplegia After Chronic Stroke: A Systematic Review.

Abstract：

OBJECTIVE:To investigate the effectiveness of neuromuscular electrical stimulation (NMES) with or without other interventions in improving lower limb activity after chronic stroke. DATA SOURCES:Electronic databases, including PubMed, EMBase, Cochrane Library, PEDro (Physiotherapy Evidence Database), and PsycINFO, were searched from the inception to January 2017. STUDY SELECTION:We selected the randomized controlled trials (RCTs) involving chronic stroke survivors with lower limb dysfunction and comparing NMES or combined with other interventions with a control group of no electrical stimulation treatment. DATA EXTRACTION:The primary outcome was defined as lower limb motor function, and the secondary outcomes included gait speed, Berg Balance Scale, timed Up and Go, 6-minute walk test, Modified Ashworth Scale, and range of motion. DATA SYNTHESIS:Twenty-one RCTs involving 1481 participants were identified from 5759 retrieved articles. Pooled analysis showed that NMES had a moderate but statistically significant benefit on lower limb motor function (standard mean difference 0.42, 95% confidence interval 0.26-0.58), especially when NMES was combined with other interventions or treatment time within either 6 or 12 weeks. NMES also had significant benefits on gait speed, balance, spasticity, and range of motion but had no significant difference in walking endurance after NMES. CONCLUSIONS:NMES combined with or without other interventions has beneficial effects in lower limb motor function in chronic stroke survivors. These data suggest that NMES should be a promising therapy to apply in chronic stroke rehabilitation to improve the capability of lower extremity in performing activities.
